How can I create json output from deep li structure

I have ol li structure as html and I want to create JSON from that but my code doesn't create that JSON I need. Can any one please help me to solve it?
I need to create JSON like that
[
{"en":"Menu1","enlink":"#enlink1","tr":"Menü 1","trlink":"#trlink1","data":[
{"en":"Menu1-1","enlink":"#enlink1-1","tr":"Menü 1-1","trlink":"#trlink1-1","data":[
{"en":"Menu1-1-1","enlink":"#enlink1-1-1","tr":"Menü 1-1-1","trlink":"#trlink1-1-1"},
{"en":"Menu1-1-2","enlink":"#enlink1-1-2","tr":"Menü 1-1-2","trlink":"#trlink1-1-2"}
]},
]},
{"en":"Menu2","enlink":"#enlink2","tr":"Menü 2","trlink":"#trlink2","data":[
{"en":"Menu2-1","enlink":"#enlink2-1","tr":"Menü 2-1","trlink":"#trlink2-1"},
{"en":"Menu2-1","enlink":"#enlink2-1","tr":"Menü 2-1","trlink":"#trlink2-1"}
]},
{"en":"Menu3","enlink":"#enlink3","tr":"Menü 3","trlink":"#trlink3"}
]
And my sample codes are..
var buildJson = function (root){
if(!root){
root='#domenu-en';
}
var result = [];
$(' ol > li ',root).each(function() {
if($(this).children("ol").length){
result.push({"en":$(this).attr("data-en"),"data":buildJson($(this))});
//return false;
} else{
result.push({"en":$(this).attr("data-en")});
}
});
return result;
}
$('#results').val(JSON.stringify(buildJson()))
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="domenu-en">
<ol>
<li data-enlink="#enlink1" data-en="Menu1" data-trlink="#trlink1" data-tr="Menü 1">
<ol>
<li data-enlink="#enlink1-1" data-en="Menu1-1" data-trlink="#trlink1-1" data-tr="Menü 1-1">
<ol>
<li data-enlink="#enlink1-1-1" data-en="Menu1-1-1" data-trlink="#trlink1-1-1" data-tr="Menü 1-1-1">
</li>
<li data-enlink="#enlink1-1-2" data-en="Menu1-1-2" data-trlink="#trlink1-1-2" data-tr="Menü 1-1-2">
</li>
</ol>
</li>
</ol>
</li>
<li data-enlink="#enlink2" data-en="Menu2" data-trlink="#trlink2" data-tr="Menü 2">
<ol>
<li data-enlink="#enlink2-1" data-en="Menu2-1" data-trlink="#trlink2-1" data-tr="Menü 2-1">
</li>
<li data-enlink="#enlink2-1" data-en="Menu2-1" data-trlink="#trlink2-1" data-tr="Menü 2-1">
</li>
</ol>
</li>
<li data-enlink="#enlink3" data-en="Menu3" data-trlink="#trlink3" data-tr="Menü 3">
</li>
</ol>
</div>
<textarea id="results" style=" height: 279px;"></textarea>

I found the solution its very simple, in case any one needed I like to share it. If we tell the jQuery select first li as ol:first >li then its generate same hierarchy as li structure.
var buildJson = function (root){
if(!root){
root='#domenu-en';
}
var result = [];
$('ol:first > li ',root).each(function() {
var itemdata = {};
$.each($(this).data(), function(key, value) {
itemdata[key] = value;
});
if($(this).children("ol").length){
itemdata["data"] = buildJson($(this));
}
result.push(itemdata);
});
return result;
}

The main difference seem to be that you don't include the other data- attributes other than the data-en. You can iterate all of the data- attributes on an element with $.each($(this).data(), function(key, value) {}).
In your case that would be something like:
$(' ol > li ',root).each(function() {
var itemdata = {};
$.each($(this).data(), function(key, value) {
itemdata[key] = value;
});
if($(this).children("ol").length){
itemdata["data"] = buildJson($(this));
}
result.push(itemdata);
});
That should give you an equal JSON result. The properties may be in a different order, but that shouldn't matter for JSON (for example: your JSON example had the order en, enlink, tr and trlink, while I got tr, trlink, en and enlink in my example. The order of the menu items in the list is still the same (1, 1-1, 1-2, etc.).

Serialize from ul li with child using jqueryui sortable

I would like to know how to create a JSON or serialize (both is fine) from a ul including
<ul class="menu send ui-sortable">
<li id="pageid_1" class="ui-sortable-handle">Inscription
<ul class="menu send ui-sortable">
<li id="pageid_2" class="ui-sortable-handle">Joueurs en ligne
<ul class="menu send ui-sortable"></ul>
</li>
</ul>
</li>
I cannot find how to create something like this:
pageid[]=1&pageid[1]=2 OR [{"pageid":1,"children":[{"pageid":2}]}]
Meaning, including parent ID in [].
Thank you for your help!

This code will produce the output required
var result = [].map.call(document.querySelectorAll('ul.menu.send.ui-sortable li.ui-sortable-handle'), function(li) {
var parent = '';
if (li.parentNode && li.parentNode.parentNode && li.parentNode.parentNode.nodeName == 'LI' && li.parentNode.parentNode.matches('li.ui-sortable-handle')) {
parent = li.parentNode.parentNode.id.replace(/\D+/g, '');
}
return "pageid[" + parent + "]=" + li.id.replace(/\D+/g, '');
}).join('&');
console.log(result); // pageid[]=1&pageid[1]=2
I haven't thought about how to do the second format, because the first format is easier to produce

How to match list items with values in an array

I have an array, it contains values [1,2].
I also have an html list
<ul>
<li id="1">List Item 1</li>
<li id="2">List Item 2</li>
<li id="3">List Item 3</li>
</ul>
I need to iterate through the array, and if a value in the array matches an ID in my list, add a class to the list item.
The output example would be
<ul>
<li id="1" class="active">List Item 1</li>
<li id="2" class="active">List Item 2</li>
<li id="3">List Item 3</li>
</ul>
I'm a bit lost on this one, thanks in advance!

Try to use $.map() to translate the array into "#1,#2" and pass it as a selector then add class to it,
var arr = [1,2]; // var arr = Express.completedSteps;
$($.map(arr,function(val,_){
return "#" + val;
}).join()).addClass('active');
DEMO

try
var arr=[1,2];
for(var i in arr){
$("#"+arr[i]).addClass("active");
}
DEMO

Try out following.
$(document).ready(function(){
var obj = [1,2,5,7];
$.each( obj, function( key, value )
{
$('li').each(function(){
if($(this).attr('id')==value)
{
$('#'+value).addClass( "active" );
}
});
});
})

JQuery find all elements with a class add their id to a coma separated list

As the title says I want to find all li tags inside an ordered list called #selectable with the class .ui-selected and add their id's to a string with each id separated by a comma.
Here's an example of what my html looks like:
<ol id="selectable">
<li id="1" class="ui-selected"><li>
<li id="2"><li>
<li id="3" class="ui-selected"><li>
<li id="4"><li>
<li id="5" class="ui-selected"><li>
</ol>

Try this:
var selectedIds = $('#selectable .ui-selected').map(function() {
return this.id;
}).get().join(',');
Example fiddle

Was working with my fiddle and couldn't figure out why my test array was returning 10 items in stead of 5. You are not closing your list items use <li></li> in stead of <li><li>.
Your source was missing a /.
I pushed them in an array and converted the array to a string with toString()
var listItems = [];
$('#selectable .ui-selected').each(function(){
var theID = $(this).attr('id');
listItems.push(theID);
});
listItems = listItems.toString();
console.log(listItems);

set order to jquery sortable

I use jquery draggble function for unorderd list (ul) and face a problem of getting the order of items after it changed and setting the order ofter page is loaded.Suppose we have the following code :
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js> </script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function(){
$('.secondblock').sortable({axis:'y'});
$(".block").sortable({
axis: 'y',
update: function(event, ui) {// order changed
var order = jQuery(this).sortable('toArray');
// set this order to .secondblock
}
});
});
</script>
</head>
<body>
<ul class="block" type="none">
<li id = "one">1</li>
<li id = "two">2</li>
<li id = "three">3</li>
<li id = "four">4</li>
<li id = "five">5</li>
</ul>
<ul class="secondblock" type="none">
<li id = "one">1</li>
<li id = "two">2</li>
<li id = "three">3</li>
<li id = "four">4</li>
<li id = "five">5</li>
</ul>
</body>
Are there any possible solutions?

First, you shouldn't have the same id appear twice in a document. That will cause all kinds of problems.
Instead, set a data-attribute on the items in the second list to reflect corresponding items in the first list:
<ul class="block" type="none">
<li id = "one">1</li>
<li id = "two">2</li>
<li id = "three">3</li>
<li id = "four">4</li>
<li id = "five">5</li>
</ul>
<ul class="secondblock" type="none">
<li data-block-id = "one">1</li>
<li data-block-id = "two">2</li>
<li data-block-id = "three">3</li>
<li data-block-id = "four">4</li>
<li data-block-id = "five">5</li>
</ul>
Then reflecting the sort of the first list in the second list is simple:
$('.block').sortable({update: sortOtherList});
function sortOtherList(){
$('.block li').each(function(){
$('.secondblock [data-block-id=' + $(this).attr('id') + ']')
.remove()
.appendTo($('.secondblock'));
});
}

Faust's looks better to me. Mark it if it's what you wanted.
Yes. I feel like I need more information, but I had to do almost the exact same thing recently.
First, you want to extend the javascript array object with a sorting algorithm. Here is what I use:
Array.prototype.move = function (old_index, new_index) {
if (new_index >= this.length) {
var k = new_index - this.length;
while ((k--) + 1) {
this.push(undefined);
}
}
this.splice(new_index, 0, this.splice(old_index, 1)[0]);
return this; // for testing purposes
};
source Move an array element from one array position to another
Then, what I would do is use this along with an OldPosition/NewPosition function to get the index of the element before and after the sort, and use this method to move the object in the array.
I think JQuery sort let's you get information about the array before and after the sort
ex:
$('li').presort(function() {
window.oldindex = $(this).index();
});
$('li').postsort(function() {
window.newindex = $(this).index();
array.move(oldindex,newindex);
});
If you're just looking to make .secondblock match .block after sort, you can do this:
source: http://jqueryui.com/demos/sortable/#events
$( ".selector" ).sortable({
start: function(event, ui) { //Get the order of the .block list items before dragging }
});
$( ".selector" ).sortable({
stop: function(event, ui) { //Get the new order of the list items after dragging. Compare the two orders and sort .secondblock to match block }
});
